Structure d'algèbre de Banach sur l'espace à poids L_ω^p(G)
Abstract
Let G be a locally compact group and ω be a weight on G. For p ∈ ]1, +∞ [, we give a necessary and sufficient condition, on ω, for L_ω^p (G) to be a Banach algebra. The case where ω is biinvariant under a subgroup K of G is also considered.
